Background: We evaluate trends in outcomes after colorectal resection over the decade of the introduction of ACS-NSQIP as well as of targeted-colectomy information. Study design: From 2007 to 2016, patients undergoing non-emergent colorectal procedures were included. Demographics, operative complexity (American Society of Anesthesiologists and wound classes); complications, early (<5 days) discharge and mortality were plotted over years. Outcomes after introduction of colectomy-targeted datasets (2013-2016) were compared to those prior (2007-2012). Multivariable analyses were performed to evaluate the impact of colectomy-targeted data on outcomes. Results: Of 310,632 included procedures, 131,122(42.2%) and 179,510(57.8%) were performed before and after the introduction of colectomy-targeted variables respectively. Most complications including surgical site and urinary tract infections, sepsis, septic shock, venous thromboembolism, respiratory complications, reoperation and mortality reduced over time with increased early discharge. On multivariable analysis, introduction of colectomy-targeted data was associated with lower surgical site (OR = 0.78,95% CI = [0.77-0.80]); systemic (OR = 0.94,95%CI = [0.91-0.98]) and urinary tract (OR = 0.70,95%CI = [0.67 -0.74]) infections; reoperation (OR = 0.88,95%CI = [0.85-0.91]) and early discharge (OR = 1.60,95% CI= [1.57-1.63]). Conclusion: Over its first decade of introduction, ACS-NSQIP has been associated with improved outcomes after colorectal surgery. The introduction of colectomy-targeted data has further improved outcomes. (C) 2019 Elsevier Inc. All rights reserved.
